[Draco]

My pom used to try to lick my face as pup never let him do too much. When he was older it was only if I asked for a kiss and do so on my cheek.
My pup draco licks everything, he's nearly 10 weeks so I think it's mainly out of curiosity. Though he does particulary love to try and like my nose, mouth, ears. My guess is mouth has leftover smells from food or something. And I've read dogs lick us in general because we taste like salt, and well boogers and all our nose stuff is extra salty. And as fars ears, well I suppose it could be a smell they can sense even if your ears are clean, but read it's also a sign of submission, and all licking seems to be a sign of affection.
